Atop a 100-foot barge tied up at the Port of Los Angeles, UCLA engineers have built a kind of floating laboratory to answer a simple question.
, can now learn if extracting that carbon from the ocean is an effective way to reverse the effects of climate change.
"Basically what we've done is taken the parameters that we've figured out in the lab and made them much bigger," said Thomas Traynor, the institute's translation leader.where a prototype would pull seawater through a mesh, allowing an electrical charge to pass into the water. A series of chemical reactions ultimately depleted the seawater of dissolved carbon dioxide in a process similar to how seashells are made.
"Not only does it teach us the technology and demonstrate that it works at bigger and bigger scales, but the scale of this problem is so big that we need to be doing this at the largest scale that we possibly can to make a difference," said Sant.Other methods of carbon sequestration rely on geological storage or increase the PH levels of the ocean.
Even a system this large needs to be 100 to a thousand times larger to have a real impact, but designs for that expansion are already underway. A commercial site could be in place within three years if all goes well.
